Application filed September 25, 1914. Serial No. 863,453.

To all whom it may concern:

Be it known that 1, WILLIAM REYNOLDS, a citizen of the United States of America, re siding in Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Bait Bearing Mountings, of which the following is a specification. I

V This invention aims to provide a practicable mounting for ball bearings for shafts which shall form a lubricating chamber such that the balls travel in a lubricating medium, such as grease or oil The provision of such a chamber involves diiliculty in making a close joint at the opening through which the shaft passes, so as to prevent the entrance of water, 'dust, grit or other deleterious substances, while at the same time allowing the necessary amount of freedom of moticn'for the shaft, which should be free to wabble or gyrate. To provide for this condition the grease chamber is composed of rigid'walls appurtenant to the stationary bearing while the end walls encircling the shaft are formed each of an annular sheet of suitable flexible material fastened at its outer margin to the rigid wall, and at its inner margin'to a stufling ring which makes free running but leak-tight contact-with a ring or collar 'tastened on the shaft. This collar is embraced between two rings fastened together from opposite sides and forming a composite ring to which the inner margin of the flexible an oozing of lubricant from the chamber; while any wabbling motion is allowed for by the flexibility of the diaphragm.

The accompanying drawings show the preferred embodiment of the invention.

Figure 1 is a longitudinal section, being mainly in a'vertical plane but partly in an oblique plane, as shown by dotted line l--l in Fig. 2. Fig. 2 is a transverse section, the right half showing the bearing in elevation, while the left hall is in section in the two planes denoted by the line 2+2 in Fig. i

is the shaft and B is the main stationary member of the bearing which may be in the form of a pillow block, or if inverted a hanger, or any other form which may be desired.

C C balls which travel as usual in race-ways formed in the inner and outer concentric rings D and E respectively.

Theparticular ball bearing here shown .is the well-knownSKl bearing, and requires no description.

At a is shown a ball spacer which may be used, or not, as desired. The ring D is shown as attached to theshaft by a screw collar F. The ring D is thus essentially a part of the shaft, and might conceivably be formed as an integral collar thereon. The ring E is shown as mounted fixedly within thelbearing B, and might conceivably be made integral therewith The particular ball bearing construction thus far described is shown merely as an illustration,

and forms no part of the present invention.

To form the grease chamber G the bearing is provided with rigid walls exmargins each diaphragm is fastened to a" stationary memberolf the stuffing rings. These rings comprise a revolving ring or member at which constitutes a collar on the shaft, being fastened thereto by screws 6; and stationary rings or. members i and g, the ring f being the one to which the inner margin of the diaphragm is fastened as by screws 71 through a ring 2''; while the ring or member 9 matesthe ring 7 and is fastened thereto by screws j. Therings f g embrace between them a portion of thecollar d forming an outward rib, and having bearingsupon thecylindrical faces of the collar, so that the latter turns freely within them. The joint thus formed is substantially leak-tight, but admits sufiicient lubricant to render the rubbing contact practi are the respective rows or series of cally frictionless. The rings 7 9 being carried solely by the collar (13 and diaphragm J are free to participate in the gyrating or Wabbling movement of the shaft, the fiexure of the diaphragm permitting this and also providing for the centering of the rings on the shaft, if the position of the latter be eccentric to that which would be assumed by: the stufling rings. The rings f g preferably extend beyond the perimeter of the rib on the ring all so as to form an annular chamber m; this chamber becomes filled with the lubricant and assists in the making of a suitable leak-tight joint.

Grease or oil may be introduced into the chamber G through a screw plug. or cap K. If grease be used, it may be filled to the level shown; oil would usually be at a lower level.

While the construction is that deemed preferable, it may be greatly varied in matters of detail without departing from .the essential features of'the invention.

I, claim as my invention 1. A shaft bearing comprising balls, members having race-ways and an inclosing member, the latter having a chamber for lubricant comprising a flexible diaphragm forming an end of said chamber, and stuffing rings encircling the shaft, one member thereof fastened as a collar upon the shaft and turning Within another stationary member thereof, to which is fastened the inner margin of said diaphragm, while its outer margin is fastened to said inclosing member.

2. A shaft bearing comprising balls, members having race-ways and an inclosing member, the latter having an annular wall inclosing the shaft, and a flexible 'diaphragm, inclosing a chamber for lubricant,

'and stuffing rings encircling the shaft, one

member thereof fastened as a collar upon the shaft and other stationary members encircling and embracing such collar to form therewith a practically leak-tight joint, said diaphragm fastened at its inner margin to thestationary members of such stuffing rings and at its outer'margin to said wall.

3. A shaft bearing comprising balls, mem-- bers having race-ways and an inclosing member, the latter comprising an annular wall inclosing the shaft, and a flexible diaphragm, inclosing a chamber for lubricant, and stufiingrings encircling the shaft, one member thereof fastened as a collar upon the shaft and having an annular rib, and two member, the latter comprising a rigid wall encircling the shaft, and a flexible diaphragm, inclosing a chamber for lubricant, and stuffing rings encircling the shaft, one member thereof fastened as a collar upon the shaft, and two stationary members encircling said collar, fastened together from opposite sides, and forming around said collar an annular chamber, and said diaphragm fastened at its inner margin to said stationary rings and at its outer margin to said rigid wall.

5. A shaftbearing comprising balls, members having race-ways, and an inclosing member. comprising a bearing part, annular walls fastened to opposite sides thereof, and flexible diaphragms applied to the outer ends of said walls and forming therewith a chamber for lubricant, and stufiing rings encircling the shaft, one member of each fastened as a collar upon the shaft and other stationary members encircling such collar, each diaphragm fastened at its inner margin to such stationary member and at its outer margin to said Wall.

6. A shaft bearing comprising walls and rings having race-Ways, the shaft fastened within the inner ring, a main bearing member encircling the outer ring, rigid annular walls fastened against oppositesides of said such collar, each diaphragm fastenedat its inner margin to such stationary member and at its outer margin to said wall.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

WILLIAM REYNOLDS.
